WARNING
• Damaged or deteriorated tools are very dangerous. Use qualified and suitable tools
only.
• Use of protectors: When disassembling, assembling, and conducting maintenance or
when handling a dangerous type of liquid or a liquid of unknown property, be sure to
wear safety gloves, a helmet, and protective shoes. In addition, when handling wetend parts, always wear protective goggles, masks, etc.
• To prevent death or injury from a falling pump, make sure the rope or chain used for
lifting the pump is not accientally cut or disconnected during installation. Make sure
the rope or the chain used to lift the pump has sufficient strength in relation to the
pump load. Also, be sure not to stand underneath a lifted or suspended pump.
• When fixing the pump with rope or chain, be sure to use special bolts (or rings) for lifting. Never use any other points for lifting the pump.
• Always turn off the power supply prior to servicing the pump. Make special provisions so that no other operator mistakenly turns on the power supply while someone
is working on the pump. In a noisy or poor visibity environment, display a sign near
the power supply switch to notify others that someone is "WORKING" on the pump.
Power supply mistakenly turned on during maintenance may lead to personal injury.
Each operator must be especially careful of power supply operation.
• To ensure greater safety, check and make sure that there is no one near the pump
when switching on the power supply. The pump is not equipped with an ON/OFF
switch. Connecting the power cable or power plug supplies the power to the pump
and starts the operation.
• Run the pump at the specified power supply voltage on the nameplate only.
Otherwise, fire or electric shock may result.
• If the pump operation is stopped due to a power failure or closure of discharge wire,
turn off the power switch at once. After normal conditions return, turn the switch on
again.
• Do not use the pump for anything that it is not designed to do. User’s failure to
observe this instruction exempts IWAKI from any responsibility for personal injury or
damage to the equipment or facility caused by the pump's misuse.

WARNING
• Do not allow toxic substances such as lubricants, solvents, or similar substances to
flow into the local sewage system or river systems. Do not drain hazardous liquids
such as chemical solutions discharged out of the pump directly onto the ground.
Instead, drain such liquids into some kind of container. Observe the laws and regulations related to the application, handling, and processing of hazardous substances.
• Do not pass under a raised pump.
Never pass under a raised pump. A serious injury could occur if the pump is accidentally dropped.
• No remodeling
Remodeling of the pump by the user may result in serious personal injury, electric
shock, or damage to the pump. Do not attempt remodeling as it is very dangerous.
• Be careful with rotating elements.
Rotating elements such as the shaft, coupling, etc., can cause a serious personal
injury by seizing fingers, hands, hair, etc. Be careful not to touch such rotating elements while the pump is in operation.
• When the pumps are used to transfer the dangerous liquids mentioned as below, the
pumps always must be checked and watched so that the liquids can not be leaked.
The operation of the pumps leaking the liquids may result in personal injury and/or
explosion, fire accidents.
• Explosive, fire-spreading and inflammable liquids
• Corrosive and stimulus toxic liquids
• Liquids detrimental to health
CAUTION
• Qualified operators only
The pump operator and pump operation supervisor must not allow any operators who
have little or no knowledge of the pump to run operate the pump. Pump operators
must have a sound knowledge of the pump and its operation.
• For specified application only
The pump is designed and manufactured to the specifications agreed upon by the
user and IWAKI. The use of a pump in any application other than those clearly specified may result in injury or damage to the pump. Use the pump strictly in accordance
with the pump specifications and application range. If you change any specification,
contact IWAKI or your dealer.

No Remodeling

CAUTION
• Ventilate
Poisoning may result during an operation which involves toxic or odorous liquid.
Ventilate the operating site sufficiently.
• Spill-out prevention measures
Appropriate protective measures should be taken against any spill-out accidents
involving the operating liquid as a result of unexpected damage to the pump or the
piping. Never discharge hazardous liquid, including, but not limited to, chemical liquid, over the ground or floor on the pump operating site. Follow local rules and regulations in disposing of hazardous substances.
• Do not operate the pump dry.
Do not run the pump dry (without liquid inside the pump). Heat generated as a result
of abrasion between elements inside the pump during operation without liquid may
damage the inside of the pump. Operating the pump with the suction valve fully
closed will result in dry operation.
• Keep away from heat or flame.
Do not place any open flame or flammable object near the pump.
• Do not stand on the pump.
Do not stand on the pump or use the pump as a step under any circumstances.
Otherwise, you may experience a serious injury.
• Do not touch the pump.
When the pump is used to feed a hot liquid, do not touch the pump or the piping with
your bare hands during and immediately after operation as their surfaces are dangerously hot.
• Arrange grounding
Do not operate the pump without connecting the grounding wire. Otherwise, an electrical shock may result. Make sure the grounding wire is connected with the grounding terminal.
• Install an earth leakage breaker
The operation of a pump without using an earth leakage breaker may cause an electrical shock. Please install an optional leakage breaker in the system.
• Countermeasure for static electricity
When low electric conductivity liquid such as ultra-pure water and fluor inactive liquid(e.g.FluorinertTM) are handled,the static electricity may be generated in
pump,which may cause static discharge and break down.Take countermeasure to
avoid and remove static electricity.

CAUTION
• Do not install or store the pump in the following places.
•
Places where flammable gas, dust or material is used or placed.
•
Places where corrosive gas (chlorine gas or the like) is generated.
•
Places where the ambient temperature is extremely high (40 °C or higher) or
extremely low, 0 °C or lower.
•
Places where the pump is exposed to extreme dust or humidity. (Excluding the outdoor type)
•
Places where vibrations occur.
• Pump start-up
When connecting a power supply to the pump, make sure there is no person around
the pump. The pump has no ON/OFF switch. The pump starts operation when the
power is supplied by connecting the power supply cable.
• Foreign matter
Should foreign matter enter the pump, turn off the power at once and remove the
obstruction. Using the pump with foreign matter inside may cause damage to the
pump or a malfunction.
• Disposal of used pump
Disposal of used or damaged pumps must be done in accordance with local laws and
regulations. (Consult a licensed industrial waste products disposing company.)
• The flange type motor is so heavy that it may fall over against the motor following disassembly of the pump. Make sure to support the motor by using a crane or other
heavy-duty support system.
• Handling of magnet coupling
The magnet used in the pump has a very high magnetic power. Be careful not to
allow your fingers to be seized by the magnet or to allow the magnet near any electronic device which may be affected by the magnet's power.
As a flange type driving magnet requires special equipment to hold it in place, do not
remove it from the shaft . In case removal is necessary, contact IWAKI or your dealer.
• Suspending pump operation for a prolonged period
When suspending pump operation for a prolonged period, drain the pump and clean
inside the pump. Take appropriate measures to prevent the entrance of foreign matter into the pump. If the pump is not operated for a period longer than one year,
replace the gasket and inspect inside the pump.

1. Before Using Pump
2. Operating Principle
The MDE pump is a magnet-driven centrifugal type pump
developed for various applications.
The impeller inside the pump chamber (front casing) is
rotated by magnetic force to transfer liquid from the suction
side to the discharge side.
The MDE type pump features excellent corrosion
resistance, durability, and safety, and serves as a chemical
pump for various processes. Most chemicals can be
handled by the pump.
